Actually, I support Provorov, imagine if there was a MAGA night.
Requiring players to publicly support political, social or religious positions and views they don't agree with is wrong, same way an employer doing that to any employee is wrong.
It's one thing to demand tolerance and manners, if he was calling players "Homophobic Slurs" or engaged in hostile behavior in any way, that should be strictly condemned and punished, but asking him to actually affirm behavior that goes contrary to his religious belief is also wrong. How would you feel if your company required you to put a MAGA sign in your front yard?
There's a difference between the right of Gay people to demand nondiscrimination, that is, they should have the same right as all Americans, to speak and live their lives freely without fear of punishment (economic or social) or violence. It's quite another to demand that those who have religious or cultural objections to such behavior to have to actively affirm that behavior as acceptable to them or lose their livelihood.
Freedom must extend to those whose believe differently than "we" do, or it's just a sham.
If we coerce people to "speak" only what we consider tolerable, we no longer believe in freedom of speech, but merely the freedom of politically correct speech.
Even hate speech should be protected, as the Supreme Court has ruled.
In 1969, the Supreme Court's decision in Brandenburg v. Ohio held that inflammatory speech--and even speech advocating violence by members of the Ku Klux Klan--is protected under the First Amendment, unless the speech "is directed to inciting or producing imminent lawless action and is likely to incite or produce such action."
I would point out that this pendulum swung the other way for most of American history, that speech that didn't correspond to the norms of a different era was suppressed, which included support for Gay rights, civil rights, socialism, anti-war, separation of church and state and other unpopular beliefs, and it took a couple centuries to firmly establish freedom of speech, and the principle of free discourse as a social norm. There was a time when the ACLU fought those battles for both the Left and the Right to engage in unpopular speech.
